Firing people into the cabin using a cannon?
Boarding by ticket price?
Using riot police to herd the uninitiated?
Using a rope instead of steps at remote stands?
Window seats board first?
Restriction on hand luggage size guaranteed aboard?
Getting US drill sergeants to bellow at dawdlers?
Only a few are serious suggestions.
If I were a betting man, I'd put some money on the hand baggage being enforced and an EasyJet policy of "only X size bags guaranteed to fit" being trialled...
